What's the ballpark cost of the hardware that you used to get those 8 BTC?

(It's interesting information for observers, of course people are turning on hardware that will run profitably, but mild opportunities aren't going to drive a whole lot of purchases)

Edit: If you have the rough 'replacement costs' floating around in your head that's interesting too. So not your actual costs, the approximate cost of bringing equivalent power online right now.
